Abstract
A cleaning tool for cleaning a surface has a core with a lower surface and an upper surface. A first set of cleaning sheets is each removably supported on the lower surface in a stacked configuration. Each of the sheets includes a bibulous layer and a moisture barrier layer. The moisture barrier layer prevents transport of liquid from one bibulous layer of one sheet to the bibulous layer of an adjacent sheet. Each of the sheets has an outward face for cleaning and an opposed inward face. The outward face of the sheets is designed to contact and clean a surface and thereby become soiled. Once the outward face of the outermost sheet becomes soiled, the sheet may be peeled away to expose a non-soiled sheet.
